The IRWIN Strait-Line Speedline Pro Chalk Reel makes marking fast, rewinding faster, and chalk refilling easier. It features a lightning fast 6:1 planetary gear ratio for rewinding 6X faster than traditional chalk line reels* for fewer breaks. and a nested hook dock for compact storage without unwanted hook snagging with the ability to quickly hook and go with gloves on. The 100 ft. hi-tensile line, robust steel handle, and large center hub deliver increased durability, strength, and torque, and the durable ABS with rubber overmold housing provides impact resistance. The new spool design reduces line jamming, knotting, and fraying for reel longetivity.
